In order to produce petroleum alternatives from biomass, a significant amount of research has been focused on oils from microalgae due to their origin, which would not affect food availability. Nanoporous hybrid catalysts composed ofnsAl2O3and zeolites have been proven to be very useful compared to traditional catalysts in hydrotreating (HT), hydrocracking (HC), and catalytic cracking (CC) of large molecules. To evaluate the reaction scheme and products from model isoprenoid compounds of microalgae oil, nanoporous hybrid catalyst technologies (CC:nsAl2O3/H-USY andnsAl2O3/H-GaAlMFI; HC: [Ni-Mo/γ-Al2O3]/nsAl2O3/H-beta) were studied. The major product from CC onnsAl2O3/H-USY was highly aromatic gasoline, while the product from HC was half-isoparaffinic/olefinic kerosene. Although more than 50 wt% of the products from HT/CC on the USY catalyst was liquefied petroleum gas due to overcracking, the product from HT/CC on the MFI catalyst was high-octane-number gasoline. Delightfully, the product from HT/HC was kerosene and its average number was 11, with more than 80 wt% being isoparaffinic. As a result, it was demonstrated that hydrotreating may convert isoprenoid oil from microalgae over nanoporous hybrid catalysts into a variety of products.

Spent earth is a waste resulting from the bleaching process which contains gums and a large amount of oil so that it still has the potential to be reprocessed into biofuel. This study aims to utilize the oil from spent earth as a raw material in the synthesis of biofuels through the catalytic cracking process. In the catalytic cracking process, zeolite and kaolin catalysts are used in the ratio (0:100); (30:70); (50:50); (70:30) and (100:0) and temperature variations of 150oC, 175oC and 200oC for 3 hours. Based on the research results, the best biofuel was obtained at a catalyst ratio of zeolite: kaolin (70:30) and a temperature of 200oC with a yield of 76.13%. The results of the biofuel characterization obtained a water content of 0.0301%, octane number 90.5 RON and a density 751 kg/m3. Analysis of biofuel composition was measured using GC-MS and it was found that the biofuel contained 4.60% C11H24, 8.99% C12H26, 22.49% C16H34, 9.54% C18H34O2 and 54.38% C19H36O3. Based on the physical and chemical properties of the biofuel as a result of cracking with zeolite and kaolin catalysts, it is in accordance with SNI for gasoline qualification.

The main objectives of the present paper are to adaptation the five-kinetic model of the catalytic cracking process and simulation the riser to predicts the FCC products yields when one of the major input variable of the process is change. The simulation and adaptation are based on the industrial data from Romanian refinery. The adaptation is realize using a computational method from Optimization Toolbox from Matlab programming language. The new model can be used for optimization and control of FCC riser.
